The U.S. antacids market size was estimated at USD 3.00 billion in 2024 and is projected to reach USD 3.73 billion in 2030, growing at a CAGR of 3.7% from 2025 to 2030. Changing dietary habits is a key factor propelling market growth over the forecast period.
Rising cases of digestive issues such as gastroesophageal reflux disease (GERD), peptic ulcers, and other stomach problems that cause acidity, indigestion, and heartburn are also expected to support market expansion. According to a report published by the CDC in December 2024, approximately 5.9% U.S. adults were diagnosed with ulcers. Other key drivers include rising awareness and easy access to over-the-counter (OTC) antacids, which provide fast and effective relief from symptoms.
In addition, lifestyle factors such as stress, smoking, alcohol use, poor diet, and obesity, all of which contribute to acid-related conditions, are expected to further influence the growth of the U.S. antacid industry. For instance, according to a report by the CDC published in September 2024, the prevalence of obesity was 40.3% among adults in the U.S. from August 2021 to August 2023. The highest rates are seen in adults aged 40-59 and those with lower education levels. Severe obesity affected 9.4% of adults, with women showing higher rates than men across all age groups.
Most product development focuses on delivery formats such as chewable, liquids, fast-dissolve tablets, and branding. Some moderate innovation comes from combo formulations or OTC-probiotic hybrids which are expected to drive the demand for U.S. antacid industry.
The U.S. antacid market is subject to the high impact of regulations, particularly because antacids are available over-the-counter (OTC). The FDA monitors formulation, labeling, and marketing claims to ensure safety and efficacy. New formulations or combinations must meet specific OTC monograph standards, and some ingredients, such as ranitidine, have been withdrawn due to safety concerns. This means manufacturers must continuously adapt to evolving regulatory guidelines, especially around product safety, recalls, and transparency.
